PC Suite is the recommended software for this according to the manual.
Problems for transferring files are:
1. Second communicator (9210i) needs its own name, so old backups are not selectable (9210).
2. Trying to copy an old backup to a new directory causes PC suite to crash.
3. Manual says that memory card backups should not be tried (9210 -> 9210i).
Documents should not be too hard to copy manually. Other internal data seems to be more problematic, is some other synchronizing software the only possibility?
